I thought your post was a joke. LOL
Yep, vittles is a 14th century word, along the side with Victuals.
My take on vittles, and seems apparent that is has to do with home cooking.
Home cooking generally indicates something prepared in the home, Don't ya think?
Now, home cooked vittles, if yer a piece off is a very welcome blessing after dusting off and watering the horse down.
Fried chicken and Potato Salad is a good start on Vittles.
I was at Wilbur's in NC a while back (food channel). Lunch was deep fried chicken gizzards, a small spot of Coleslaw, and they never did provide the Ribs I ordered.
It just shows various element you may have to deal with.
